The fear of while you are taking a shit you have the feeling a spider will crawl from under your toilet seat or anywhere inside the toilet and bite you on the asshole, usually prompting you to flush once or even twice before you sit down to shit.
"I was in the mall and had to use the public restroom but analracnidphobia hit me and I had to flush twice before sitting down."
